Sapphire Radeon x1950 Pro

"The Sapphire Radeon x1950 Pro uses the RV570 at 575Mhz and has 512MB GDDR3 memory running at 1380Mhz. The Sapphire Radeon x1950 Pro has a 256Bit Memory Interface, 36 Pixel Shaders and DirectX 9.c support."

"This is a very interesting result and shows the benefit of having 512MB GDDR3 memory compared to 256MB GDDR3 memory. Another important point to make is the power of the x1950 Pro GPU which just blows away the x1800 GTO and x800 GTO video cards. In the end the Sapphire Radeon x1950 Pro outperforms the Connect3D Radeon x1950 Pro by 8%, the Sapphire Radeon x1800 GTO by 32% and the Sapphire Radeon x800 GTO by 53%."
